permanent, I determined to go in for what are called locums for the time being.
It must have been about the third day after I took up the work that I was sent for to "Heath Crest." I remember the morning well. I had gone after breakfast to a patient of the poorer class out at Hendon, which was about the periphery of Walland's district, and enjoyed a glorious free-wheel first down the Bishop's Avenue, and then, after a short pull up the North Road, down again by way of Finchley, and passing the house on my way over the Heath I felt a longing to examine it from the inside. It was not for any great beauty it possessed, for

Dr. Walland had said he might die in one of them. Did I think that excessive worry would be likely to cause them? etc. etc. She seemed, indeed, to carry a perfect diary of her husband's symptoms in her head, so much so that when I expressed a wish to see the patient for myself she continued her history all the way upstairs, and even into the sick-room.
Mr. Fahbwerker was certainly very ill, and when I came to examine him I could make allowances for even a greater degree of excitement than his wife displayed. Cold and
